Sigismund I the Old, Grosz 1545, Kraków - from the collection of Tadeusz Kałkowski - RARE

Coin from the collection of Tadeusz Kalkowski, author of the excellent work: "A Thousand Years of Polish Coinage".

Rarer, late vintage of the crown grosz of Sigismund the Old.

Very rare variant of the crown (8b - with a rim decorated with rectangular jewels) and a cross before the date.
In the catalog of Grzegorz Romanczyk the HIGHEST degree of rarity - RRRR.

A very nice piece, in a beautiful noble patina.

Definitely recommended.
